Context
Found during the v13.3 manual sweep on dev af81fc0f86. examples/table/covid, apps/covid and apps/sharedcovid set sortable: false on their # column. One click on that header still shows a sort arrow and sorts the Store by index. In the covid table this runs into the collection defect #19800, so the table empties and no header sorts after that. Reproduced from a fresh load: Country sorts, then #, then Cases changes only its own arrow.
The Problem
grid.header.Button#onClick (src/grid/header/Button.mjs:407) and table.header.Button#onClick (src/table/header/Button.mjs:379) cycle isSorted without reading sortable. afterSetIsSorted then shows the arrow and fires sort, and the container sorts the Store. sortable itself only toggles neo-sort-hidden (afterSetSortable, grid :374, table :227), and the click's isSorted change undoes that.
The Architectural Reality
sortable reaches each button from the grid or table Container and from its header Toolbar (createItems and the runtime afterSetSortable hooks).onClick also calls super.onClick(data), the Button handler, which has to keep running for a non-sortable header.- Design authority:
afterSetSortable(false) hides the sort glyph, and three shipped tables set sortable: false on a column that must not sort.
The Fix
Both onClick methods cycle isSorted only while sortable is true. super.onClick(data) still runs.
Acceptance Criteria
Out of Scope
- The collection emptying on a sort by
index, #19800. This ticket only stops a non-sortable header from starting a sort.
